While it is offering customization options, such as a choice of seats and LED lighting, of which there are 16.7 million different colors on offer, Airbus is hoping its new customization centre in Hamburg plus a catalogue of specific options will reduce potential delays.

Suppliers are also certified ahead of being included in the catalogue, another measure to prevent delays.

"A high level of customization is a value-destroyer, especially on the wide bodies," Robert Korn, co-founder of investor Apollo Aviation, which acquires mid-life and mature aircraft, said at a conference earlier this year.

For example, Emerson said, the cabling on the A350's in-flight entertainment system allows each seat to be moved by four inches, thus saving costly re-wiring should a new owner of a plane wish to reconfigure seat spacing.

At present, it takes customers around 20 months to design their cabin interiors for the A350. Emerson said the aim was to get this down to just under a year once production is in full-swing. That compares with a current time frame of 18 months for the larger A380.

Airline customers spend two weeks at the new design centre in Hamburg at the start of the cabin design process, making choices regarding seat spacing, fabrics, lighting, lavatory locations and even how many coffee machines to have on board.

The centre allows customers to see mock-ups of cabins and create 3D digital images, something which Airbus hopes will reduce last-minute design changes.

Responding to queries as to whether there was enough choice for airlines, Didier Nasarre, head of the A350 customer program, said the catalogue was continually evolving and had already doubled in size in the last year.
